CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 394,096, dated December4, 1888.

Application filed July 2 7, l 8 8 7.

T0 all whom it may concern.-

Be it known that we, WILLIAM HENRY BUR- DEN and FREDERTCK CHEEVERBURDEN, of Cleveland, county ot Cujfahoga, State ot' Ohio, have inventedcertain new and uset'ul lmprovements in Car-Journal Lubricators, ot'which the following is a speciticatioii.

This invention relates to a device for conveying oil to the journals incar-axle boxes; and it consists in the peculiar construction andcombination ot' the parts adapted to be placed in the journal-box belowthe journal for feeding oil to the central part ot the journal in smallquantities sufficient to lubricate the journal without waste. It is alsoso constructed to exclude dust and dirt from the oil, and is arranged tooperate in combination with the journal, substantfialljv as hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure l is a if'ertical and longitudinalsection ot' a carjournal-box having our device attached, showing itslocation and manner ot' working in connection with the journal, Fig. 2is a vertical cross-section on line 2 2 ot' Fig. 1. Fig. P3 is a top orplan view of our lubricating device detached. Fig. et a side elevationot' the same, partly in section, showing an inner cup or chamber forholding oil. Fig. 5 is a detached sectional view of the feed-roller.

A represents a car-journal box, and l is the journal. C is the bearingAfor the journal. These may be of the common and well-known kinds andconstruction.

Our device is constructed as follows:

D is a frame or plate having an upright flange, E E, at each end. To thesaid vflanges are secured, byrivets or other suitable means, plates ofheavy leather, F F, or other suitable material, preferably leather, onaccount of its elasticity. The upper sides ot the said flanges E andplates F are cut out to fit up and partly embrace the journal B. To theunder side of the plate or frame D is secured a spring, G, which alsobears upon the bottom of the box and serves to support and hold thedevice up to the journal.

H is a feed-roller, consisting' of a worm- Serial No. 245,409. (Nomodel.)

wheel and shaft set in bearings I l on the under side of the frame orplate D.

J .l are two rings located one on cach side of the worm-wheel, and areattached bvlneans of diagonal spokes, forming cone shaped frame-work ateach side ot' the said worinwhecl. The rings .I J are ot a littlegreater diameter than the worin-wheel, and they, t0- gether with theworin-wheel, project a short dist-ance above the trame D through anopening t'or that purpose, and the said rings onljv are in contact withthe journal l, by which the said feed-roller derives its rotary motion.

K is a volte having eyes which lit on the shaft of feed roller looselyand permit freedom of play thereon, while the arm k of the voke may lieon the bottom of the box.

L is a gear-wired journaled on a pin or rivet, R, in the lvolte, andwith its teeth meshing with the wor1nwheel, and from which saidgear-wheel derives rotary motion. The yoke is made in two parts, and therivet R, which serves as the pivot for the gear-wheel, also serves tosecure the two parts of the yoke together.

It desired, an inner box, M, fitted to hang suspended from the frame Dand within the spring G, to contain the oil and the mechanism forfeeding it, may be employed for the purpose of providing a safeguardagainst the ingress of dirt.

The operation of this device is as follows: The revolutions of thejournal B imparta rotarjv motion to the feed-roller H, and from thenceto the gear-wheel L, which reaches down into the oil. The oil is thusconveyed in the teeth of said geaiwheel to the wormwheel, from which itis taken up by the journal b v capillary attraction at its middle part,and therebyv supplying the lubricant to the journal-bearings.

From the foregoing' it will be seen that this device possesses thefollowing advantages. It feeds the oil in small but sufcient quantityand to the central part of the journal, from whence it is equallydistributed along the bearing. It accommodates itself to position underthe journal under all conditions, preserving the alignment of thefeed-roller with the journal, thus avoiding friction. It incloses theoil in a practically-tight box, thus securing it against the ingress ofdust or dirt, there by preserving the oil free from grit.

Having described our invention, We claim as follows:

lr. The feed-roller consisting of a shaft li aving a Worin-Wheel on itscentral part, and the rings flanking said Worin-Wheel and attached bydiagonal spokes, substantially as described.

2. The Afeed-roller consisting of a shaft, Worm-Wheel, and rings, asdescribed, and a gear-Wheel pivoted to a yoke fixed on the shaft of saidfeed-roller and meshing with the said Worin-wheel, substantially asdescribed.

3. The feed-roller consisting of' a shaft, a Worm-Wheel, and rings, asdescribed, a yoke fixed on the shaft of said roller and carrying thegear-Wheel, in combination With a plate or franie having the curved-outflanges and end plates and supported on a spring constructed andoperating substantially as and for the purpose specified.

4. The end plates, in combination with the frame or plate supporting afeed mechanism in a journal-box, whereby dust and dirt are excluded fromthe journal, substantially as described.

5. The end plates, in combination with the flanges of the frame orplate, each having the curved-out space, substantially as described.

'6. The feed -roller consisting of a shaft, Worin-Wheel, and' rings, asdescribed, a yoke fixed on the shaft of said feed-roller and carryingthe gear-Wheel, in combination With a plate or frame having thecurved-out flanges and end plates, the supporting-spring, and an innerbox or cup containing oil and inclosing the feed mechanism,substantially as described.

7. The end plates attached to the fianges and each having the curved-outspace, in combination with the feed-roller consisting of a shaft,worm-Wheel, and rings, as described,
